Hello!

My first post to the list :)

I recently started learning C and know a bit of
python, so this is a nice practice for me.
Hopefully not too much over my head ;)

I'd like to add a very simple option to ffmpeg to
be able to at least write the most basic EXRs.
Currently I'm going through the info on the
website and the EXR reader made by Jimmy
Christensen.

I'll be lurking the list for a while...

One question already rose, after looking at
the docs. OpenEXR assumes that colour
values are stored as linear light as opposed to
most video codecs using a gamma value
embedded in the colour values.

Is there any 'awareness" of ffmpeg internally
of colourspaces and gamma values?

thanks in advance,

Arno
